VO2 nanoparticles powder ultrafine Thermotropic phase change material

VO2 nanoparticles powder

Description:

Vanadium dioxide (V02) is an important class of thermally induced phase change oxides. Under certain conditions, its crystal structure can be transformed from a high-temperature tetragonal rutile structure to a low-temperature monoclinic structure, resulting in 4-6 mutations in its resistivity Order of magnitude, so VO2 has important application value in thermistor materials, photoelectric switches, optical storage, and smart coatings. However, under normal circumstances, the phase transition temperature of VO2 is about 68 °C, which has important application value from the normal field. However, under normal circumstances, the phase transition temperature of VO2 is about 68 °C, which is still fixed from the normal temperature application. gap. Transition metal or rare earth ion doping can reduce the phase transition temperature of V02 material. There is still a certain gap. Transition metal or rare earth ion doping can reduce the phase transition temperature of V02 material. Nano-processing of VO2 materials can also give VO2- some novel characteristics associated with size and nanostructure.
